Oil for a Pro7 car in Northern California?

I just bought a Pro7 car to use at open track days, and for attempting to obtain a racing license.

What weight oil should I be running?

I'm in Sacramento, and will mostly use the car at Thunderhill, Infineon (Sears Pt), and Laguna Seca some day.

Thanks,

Todd

I run Valvoline 20/50 VR1 Racing in Texas. Winter and summer. Also 1oz per gallon of Amsoil 2-cycle racing in the gas.

I run 30wt Redline synthetic in my FC ITS car..

Are you going to run with NASA or with SCCA? If you decide to run with NASA, look me up at the track.. I've got the #33 Yellow and White RX-7 running in ProSedan 1

This is the same stuff we used when we ran dino oil. Now we use a mixture of 10w30 and 10w50 Mobil 1 synthetic, or Castrol Synthetic, depending on which is cheap at Wal-Mart.

I would be curious to see how many racers run synthetic motor oil.
On a side note, I did notice my idle jump 400 rpm using synthetic 2-cycle oil as a premix.

For the longest time, we didn't run it because our favorite Rotary Expert said not to. After looking around, there were a lot of people running it in Production engines, and had been for 5+ years. So, we decided to throw it in my car (figuring if it blew, we'd actually be ahead ). The butt dyno said it had a little more torque, and the pitch of the exhaust note changed. After a few thousand miles and no blowage, we put it in dad's racecar. He said he felt basically the same effects I did in my streetcar.

The reasoning behind not running Synthetic (and I believe this is from Mazdatrix) is that all synthetic oils burn, but not all of them burn clean. Since the rotary injests a little crankcase oil all the time, it's essential that it burns clean. However, if you disable the oiler and premix, I see no reason whatsoever not to run synthetic.

I don't know how many of the local guys run synthetic, but I wouldn't imagine very man of them do. Premixing didn't really catch on until a year or two ago, if that gives you an idea of how on top of things we Spec7 guys are

Thumbs up Thanks for the replies.

I ran Valvoline 20/50 VR1 Racing and I used Valvoline 2 stroke premix in the gas, since that's the best Kragen had. Seemed to run just fine, no smoke what-so-ever.

I ran the car at Thunderhill Mon 3/8, with www.clubz.org. It was my first time driving the car, ever.

The car was a blast, not a problem to be found.

I'm looking in NASA, since they run more things up here in Northern California.
